Description

Technical Field

[0001] This application relates to the field of irrigation systems, and in particular to a farmland irrigation system for water conservancy projects. Background Art

[0002] The farmland irrigation system is an important part of the farmland water conservancy project. In the modern agricultural system, the operation mode of irrigating crops by using the farmland irrigation system has basically replaced the traditional operation mode of manually irrigating crops.

[0003] In the related art, the farmland irrigation system includes a plurality of irrigation water pipes laid on the ground, and a plurality of irrigation nozzles are installed on each irrigation water pipe. When irrigating crops through the farmland irrigation system, it is necessary to pump the irrigation water into each irrigation water pipe through a water pump and a water delivery pipeline, and then spray it out through a plurality of irrigation nozzles on the irrigation water pipe to achieve the irrigation of crops in various parts of the farmland. Among them, the irrigation water used for crop irrigation mainly comes from various river ditches near the farmland.

[0004] In view of the above related art, currently, the irrigation water of the farmland irrigation system comes from the river ditch, and the water source usually contains more sediment impurities. During long-term use, sediment and debris are very likely to block various pipelines of the farmland irrigation system, resulting in difficult water output or even no water output, affecting the overall irrigation operation. Therefore, there is room for improvement. Utility Model Content

[0005] In order to reduce the situation that sediment impurities block various pipelines of the farmland irrigation system, this application provides a farmland irrigation system for water conservancy projects.

[0006] A farmland irrigation system for water conservancy projects provided by this application adopts the following technical solutions:

[0007] A farmland irrigation system for water conservancy projects includes a water storage tank and a plurality of irrigation water pipes;

[0008] A water inlet pipe is connected to the top of the water storage tank, and the end of the water inlet pipe far from the water storage tank is connected to a river ditch; a water pump is installed on the water inlet pipe; a filter cylinder is installed at the connection between the water inlet pipe and the water storage tank, and the filter cylinder is connected to the water inlet pipe through a connection component;

[0009] A submersible pump is also installed in the water storage tank;

[0010] The top of the water storage tank is open to form an open end, and a cover plate for sealing the opening is also provided on the top of the water storage tank;

[0011] A plurality of irrigation nozzles are vertically connected to each irrigation water pipe; a plurality of the irrigation water pipes are all connected to the submersible pump.

[0012] By adopting the above technical solution, during irrigation operations, the water source in the river ditch is pumped into the water inlet pipe through the water pump on the water inlet pipe. After being filtered by the filter cartridge at the end of the water inlet pipe to remove sediment and impurities, it flows into the water storage tank. Then, the water source is pumped into various irrigation water pipes through the submersible pump in the water storage tank, and finally sprayed out through various irrigation nozzles on the irrigation water pipes. The filter cartridge at the end of the water inlet pipe intercepts sediment and impurities in the river ditch water source, thereby effectively reducing the situation of irrigation water pipes being blocked by sediment and impurities. The filter cartridge is detachably installed on the water inlet pipe through the connecting component, facilitating the removal of the filter cartridge from the water inlet pipe in the later stage to clean the sediment and impurities filtered by the filter cartridge. Through the opening at the top of the water storage tank, it is convenient to enter the water storage tank through the opening to clean the filter cartridge and the inside of the water storage tank in the future. By blocking the opening with the cover plate, it is beneficial to reduce the situation of sundries falling into the water storage tank through the opening at the top of the water storage tank.

[0013] Preferably, one end of the water inlet pipe penetrates into the inner cavity of the water storage tank, and the connecting component includes a main flange and a sub-flange; the main flange and the sub-flange are respectively coaxially sleeved and fixed on the adjacent ends of the water inlet pipe and the filter cartridge, and the main flange and the sub-flange are connected by a plurality of bolts and nuts.

[0014] By adopting the above technical solution, the filter cartridge is detachably installed on the water inlet pipe. When the filter cartridge is disassembled and cleaned later, the bolts and nuts between the main flange and the sub-flange are removed, and the filter cartridge and the water inlet pipe can be separated, facilitating the disassembly and cleaning of the filter cartridge.

[0015] Preferably, an annular stepped groove is formed at the open end of the water storage tank, and the cover plate is embedded in the annular stepped groove.

[0016] By adopting the above technical solution, a reliable connection between the cover plate and the open end of the water storage tank is achieved, reducing the displacement of the cover plate during use. When the filter cartridge or the inner cavity of the water storage tank needs to be disassembled and cleaned later, the cover plate is removed from the annular stepped groove, and the water storage tank can be opened.

[0017] Preferably, a plurality of long strip water permeable holes are evenly formed on the cover plate.

[0018] By adopting the above technical solution, during daily rainy days, rainwater and the like can fall into the inner cavity of the water storage tank through the long strip water permeable holes for storage, so as to use part of the rainwater as the irrigation water source, which is beneficial to improving the utilization rate of rainwater.

[0019] Preferably, a filter net is further arranged on the bottom side of the cover plate, and the filter net covers a plurality of the long strip water permeable holes.

[0020] By adopting the above technical solution, the filter net filters out external sediment, withered leaves and other sundries, reducing the situation that external sediment or withered leaves and other sundries fall into the inner cavity of the water storage tank through the long strip water permeable holes during the daily use of the water storage tank, resulting in the pollution of the irrigation water in the water storage tank.

[0021] Preferably, a sewage discharge pipe is further connected to the bottom of the inner cavity of the water storage tank, and an electric valve and a sewage pump are installed on the sewage discharge pipe.

[0022] By adopting the above technical solution, when flushing the water storage tank subsequently, the electric valve on the sewage discharge pipe can be opened and the cleaning wastewater in the water storage tank can be pumped out to the outside of the water storage tank through the sewage pump, which is convenient for cleaning the cleaning wastewater in the water storage tank.

[0023] Preferably, an overflow pipe is further connected to the top of the water storage tank, and one end of the overflow pipe far away from the water storage tank is connected to the underground sewage pipe network.

[0024] By adopting the above technical solution, when the water level in the inner cavity of the water storage tank is relatively high subsequently, the excess irrigation water can be discharged out of the water storage tank through the overflow pipe, reducing the situation that the irrigation water overflows outside the water storage tank due to the too high water level of the irrigation water in the water storage tank.

[0025] Preferably, a plurality of electric heating plates are installed in the water storage tank, and a heat preservation cotton layer is wrapped on the irrigation water pipe.

[0026] By adopting the above technical solution, by installing electric heating plates in the water storage tank and wrapping the irrigation water pipes with heat preservation cotton layers at the same time, it is beneficial to reduce the freezing phenomenon of the irrigation water in the water storage tank and the irrigation water pipes in subsequent low-temperature weather, resulting in the situation that the farmland irrigation device cannot be used normally.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. The irrigation water pumped into the water inlet pipe by the water pump from the river ditch can flow into the water storage tank for storage after being filtered by the filter cylinder at the end of the water inlet pipe to remove sediment and sundries, effectively reducing the situation that the subsequent irrigation water pipes are blocked by sediment and sundries.

[0029] 2. By installing the filter cylinder at the end of the water inlet pipe through the connecting component, the filter cylinder can be detachably installed on the water inlet pipe, which is convenient for subsequent disassembly of the filter cylinder to clean the sediment and sundries filtered in the filter cylinder.

[0030] 3. By connecting an overflow pipe to the top of the drainage tank, the excess irrigation water in the subsequent water storage tank can be discharged in time through the overflow pipe, which is beneficial to reducing the situation that the irrigation water overflows outside the water storage tank due to the too high irrigation water level in the water storage tank.

Specific implementation manner

[0036] The following further elaborates on the present application in conjunction with the attached Figures 1-3 drawings.

[0037] The embodiment of the present application discloses a farmland irrigation system for water conservancy projects. Referring to Figure 1 and Figure 2 , it includes a water storage tank 1, a water distribution pipe 20 and a plurality of irrigation water pipes 2; the top of the inner cavity of the water storage tank 1 is communicated with a water inlet pipe 3, one end of the water inlet pipe 3 away from the water storage tank 1 is communicated with a river ditch, and a water pump 31 is installed on the water inlet pipe 3; a filter cartridge 32 is installed at the connection between the water inlet pipe 3 and the water storage tank 1. A submersible pump 4 is installed at the bottom of the inner cavity of the water storage tank 1; the water outlet end of the submersible pump 4 is communicated with the water distribution pipe 20 through a water supply pipeline; a plurality of sprinkler heads 21 are vertically and upwardly communicated with the irrigation water pipes 2 along the axial direction of the irrigation water pipes 2; a plurality of irrigation water pipes 2 are all communicated with the water distribution pipe 20.

[0038] The filter cartridge 32 is used to filter the river ditch water source pumped into the water storage tank 1 first, reducing the content of sediment and sundries in the subsequent irrigation water source in the water storage tank 1, which is beneficial to reducing the situation of the irrigation water pipes 2 being blocked by sediment and sundries.

[0039] The water storage tank 1 is buried underground; the floor area occupied by the water storage tank 1 is effectively reduced. The top of the water storage tank 1 is provided with an opening to form an open end, and the open end of the water storage tank 1 extends out of the ground. The setting of the open end at the top of the water storage tank 1 facilitates subsequent operators to enter and exit the water storage tank 1 through this open end for cleaning the inner cavity of the water storage tank 1 and disassembling and washing the filter cartridge 32.

[0040] One end of the water inlet pipe 3 penetrates into the inner cavity of the water storage tank 1; the filter cartridge 32 is connected to one end of the water inlet pipe 3 located in the inner cavity of the water storage tank 1 through a connecting component. The connecting component includes a main flange 33 and a sub-flange 34. The main flange 33 and the sub-flange 34 are respectively coaxially fixed to the outer peripheries of the adjacent ends of the water inlet pipe 3 and the filter cartridge 32. The main flange 33 and the sub-flange 34 are connected and fixed by bolts and nuts. Through the above settings, the filter cartridge 32 is detachably installed at the end of the water inlet pipe 3, facilitating the later operation personnel to remove the filter cartridge 32 from the end of the water inlet pipe 3 to clean the sediment and sundries filtered by the filter cartridge 32. In other embodiments, the filter cartridge 32 and the water inlet pipe 3 can also be connected by a threaded structure.

[0041] Refer to Figure 1 and Figure 3 , a cover plate 11 for covering the top opening of the water storage tank 1 is also detachably connected to the top of the water storage tank 1. During daily operations, the top opening of the water storage tank 1 is temporarily blocked by the cover plate 11 to reduce the situation of sundries and the like falling into the water storage tank 1 and polluting the irrigation water source. An annular stepped groove 10 is formed at the top opening end of the water storage tank 1, and the cover plate 11 is embedded in the annular stepped groove 10 to realize the reliable connection between the cover plate 11 and the water storage tank 1.

[0042] The cover plate 11 is also evenly provided with a number of long strip water permeable holes. The setting of the long strip water permeable holes facilitates the filter water tank to collect rainwater through a number of long strip water permeable holes on the cover plate 11 during rainy days for use as subsequent irrigation water sources, which is beneficial to improving the utilization rate of rainwater by the farmland irrigation system.

[0043] A filter net 12 is also fitted at the bottom of the cover plate 11. The filter net 12 covers a number of long strip water permeable holes on the cover plate 11, facilitating the interception and filtration of sundries such as sediment and fallen leaves from the outside through the filter net 12, thereby reducing the situation of sediment and fallen leaves and other sundries falling into the inner cavity of the water storage tank 1 through the long strip water permeable holes. The four top corners of the filter net 12 are fixed to the bottom side of the cover plate 11 by bolts, realizing the fixation of the filter net 12 on the bottom side of the cover plate 11.

[0044] An overflow pipe 5 is also communicated with the top of the inner cavity of the water storage tank 1. The connection between the overflow pipe 5 and the water storage tank 1 is set higher than the connection between the water inlet pipe 3 and the water storage tank 1. One end of the overflow pipe 5 away from the water storage tank 1 is communicated with the underground sewage pipe network. When the water level in the water storage tank 1 rises to the overflow pipe 5 later, the excess irrigation water can be directly discharged into the underground sewage pipe network through the overflow pipe 5, reducing the situation of the irrigation water in the water storage tank 1 overflowing to the outside of the water storage tank 1.

[0045] A drain pipe 6 is also connected to the bottom of the inner cavity of the water storage tank 1. An electric valve and a sewage pump are installed at one end of the drain pipe 6 close to the water storage tank 1. Specifically, the electric valve is an electric butterfly valve. The end of the drain pipe 6 far from the water storage tank 1 is connected to the underground sewage pipe network. Through the above settings, when flushing the water storage tank 1 subsequently, the electric valve can be opened, and the sewage pump can be used to timely discharge the cleaning wastewater generated when flushing the water storage tank 1 out of the water storage tank 1.

[0046] A number of electric heating plates are installed in the water storage tank 1; both the water distribution pipe 20 and the irrigation pipe 2 are wrapped with a heat preservation cotton layer 22. Through the above settings, it is beneficial to reduce the situation that the irrigation water in the water storage tank 1, the water distribution pipe 20 and the irrigation pipe 2 freezes due to too low temperature subsequently, resulting in the inability to use the farmland irrigation system. At the same time, a metal mesh is also sleeved on the outer periphery of the water distribution pipe 20 and the irrigation pipe 2. The metal mesh and the heat preservation cotton layer 22 are bundled and fixed on the outer periphery of each pipeline through a number of cable ties. Through the setting of the metal mesh, it is convenient to improve the overall strength of the water distribution pipe 20 and the irrigation pipe 2, and further reduce the deformation and damage of the water distribution pipe 20 and the irrigation pipe 2 due to trampling during subsequent use.

[0047] The implementation principle of the embodiment of this application is as follows: The water pump 31 pumps the water in the river ditch into the water inlet pipe 3. After filtering out sundries such as sediment in the water through the filter cylinder 32, it flows into the water storage tank 1 for storage. When irrigating crops subsequently, the filtered irrigation water stored in the water storage tank 1 is pumped into the irrigation pipe 2 through the water distribution pipe 2 by the submersible pump 4, and finally sprayed out through the nozzles 21 on the irrigation pipe 2 to realize the irrigation operation of the crops.

[0048] The filter cylinder 32 at the end of the water inlet pipe 3 is used to filter the water source in the river ditch, effectively reducing the sediment and sundries in the irrigation water source, and thus being beneficial to reducing the situation that various pipelines such as the subsequent irrigation pipe 2 and the water distribution pipe 2 are blocked by sediment and sundries.

[0049] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of this application should be covered within the protection scope of this application.
